l Claim.

This invention relates to slide shelves, and more particularly to a guide construction therefor. Shelves such as those to which this invention relates are generally provided in desks of all kinds,

of wood as well as of metal. In metal desks, however, the guide construction has generally been rather complex and expensive of manufacture, and it is, therefore, a general object of my invention to provide a novel construction which is much simpler and less expensive to manufacture than any of which I am aware.

It is an object of my invention to provide a construction as above outlined which will involve only a simple stamping operation. It is another object of my invention to provide a construction of the class described, in which the guiding elements for the sliding shelf are integral withthe top spreader of the desk pedestals. Further objects of my invention include the provision of a simple shelf construction, cooperating with the guide construction in a positive manner, to avoid jamming or springing.

These, and other objects of my invention which will be pointed out hereinafter or which will become apparent as the description proceeds, I accomplish by that certain construction and arrangement of parts, of which I shall now describe an exemplary embodiment.

Reference is now made to the drawing forming a part hereof, and in which:

30 Figure 1 is a front elevation of a desk to which my invention is applied;

Fig. 2 is a partial cross-sectional View, taken on the line 2 2 of Fig. l;

Fig. 3 is a cross-sectional View taken on the line 3-3 of Fig. 2;

Fig. 4 is a cross-sectional View taken on the line 4-4 of Fig. 2; and,

Fig. 5 is a partial perspective view of a spreader, showing the guide construction in detail.

Briefly, in the practice of my invention, I provide a desk, which may be of the type shown in Fig. l, having sliding shelves, generally indicated at III. These shelves, as will appear from a consideration of Fig. 2, ride between the top spreader II, and the desk top proper I2. The spreader II may consist generally of a piece of sheet metal of rectangular shape, having its rear edge bent downwardly, as at I3, its lateral edges bent up as at I4 and spot welded or otherwise fastened to the side ywalls of the pedestal, and its front edge bent downwardly and inwardly as at I5 and I6 respectively to provide a nished appearance.

It will be understood that the bends, just described l serve to impart stiffeners to the spreader II.

The shelf I0 may be constituted of -a piece of rectangular sheet metal having its lateral edges bent downwardly and inwardly as at I1 and I8 respectively, and its front edge bent downwardly as at i9, and reversely as at to provide a ngerhold whereby the shelf may be withdrawn. Angle members of stops 2i are spot welded or otherwise secured to the underside of the shelf I0. The function of the stops 2i will be described more fully hereinafter.

In order to guide the shelf and retain it in position, I provide the construction shown in detail in Fig. 5. Guide rails 22 are struck up from the material of the spreader I I, and are bent over as shown. Ribs 23 connecting the guide rails 22 and the plane of the spreader II .are also struck up. If desired, the construction of Fig. 5 may readily be accomplished by a single stamping operation. It will be clear that the ribs 23 serve to strengthen the guide rails 22 against the bending. While I have shown two guide rails si struck up on each side, it will be understood that more than two may be provided if desired, or that a single long guide rail may be utilized; I have, however, found the construction illustrated to be entirely satisfactory. As will be clear from a consideration of Fig. 4, the portions I8 of the shelf Ii) ride under the struck up guide rails 22, whereby the shelf It is retained in proper horizontal position and is free to be slid inwardly or outwardly,

A stop block 2li is fastened to the spreader II by means of screws passing through slots 26 in the spreader. The limits of inward and outward sliding movement of the shelf are iixed by engagement of the stops 2| with the stop block 24. If it is desired to remove the shelf entirely, it is only necessary to loosen the screws 25 and slide the block 24 along the slots 26, where it will clear the stop 2|.

It will be understood that numerous variations and modifications may be made without departing from the spirit of my invention. I, therefore, do not intend to limit myself otherwise than as pointed out in the claim which follows.

Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, is:

In a pedestal type desk having a spreader extending across the top of a pedestal, and a sliding shelf riding on said spreader, stops on the under side of said shelf, and a stop block mounted on said spreader, said mounting comprising a slot in said spreader transversely thereof, and a fastening element passing through said slot and engaging said stop block, said slot being of such length that when said fastening element is loosened and the stop block moved transversely of said spreader to the other end of said slot, said block will clear said stops whereby said shelf may be removed.
